Hey, Firstly, [NPC] Weapons Holder This dude who follows you around holding things you cant hold when your inventory is to full. When you need him you click him and his inventory opens. He also fights for you. Secondly, [Mob] The ghust The ghust, is a huge cloud-like-figure who lurkes around the map, when he sees a house, bigger than a certain size he will try and blow it down / knock pieces off it, your job is to kill him before he destroys your house badly (I dont think he should actually destroy the house completely, just knock blocks off at a time).
Um, it would be pretty obvious. it would be like a huge cloud. Edit: And it would only attack the house if your in it. it would be slack if it destroyed it while u where out
Okay, i still don't like the idea due to the many number of times i have quit a game due to all my hard-work being destroyed, but okay!
